global: update to 6.6.2.

Version 6.6.2 - February 9 2018

[INCOMPATIBLE CHANGES]
o gozilla: Deleted the following undocumented functions to reduce or eliminate
  possibility of future security risks. These were inherently unnecessary as
  source code tagging system.

  $HOME/.gozillarc
        Alias file. Please read the source code for details.
  BUGS
        Gozilla can accept not only source files but also text files,
        directories, HTML files and even URLs, because it is omnivorous.

[FIXED BUGS]
o geco.rc: gecoless always failed with a message 'geco: percol, peco or fzf is \ 
required.'
  Now, it works.
o gtags-cscope: did not accept function '9' in the line mode. This caused vim8 \ 
to hang.
  Now it accepts function '9' and reports an error message.
